i have an 04 raptor i had a white brothers r-4 on it but it was too loud i was wondering if i could by a white brothers e2 and keep the r-4 headpipe will it work thanx [img]i/expressions/face-icon-small-confused.gif[/img]

 

Why not just repack the R4? I did mine, the packing cost less than 10 bucks.

 

do you mean just buy more and add it to whats already in there or just take the old stuff out and put new stuff in
and how would i do that just open the canister and replace it? [img]i/expressions/face-icon-small-confused.gif[/img]

 

it should fit becaus my friend bought a white brothers e series slip on and then he bought the header a month latter and it all worked out
